Good advice - but I'd switch the order around a bit - use PythonCard to 
learn how to program in Python, I find an easy to use GUI much more 
friendly for learning. And I'd leave py2app until later.

PythonCard comes with a tool (standaloneBuilder) which does a good job 
of easing the problems of building distributable executables for Windows 
and Linux. The Beta version of it is much improved to offer a choice of 
tools - and the next step after that will be to add py2app support. So 
it's not there today - but there is light at the end of the tunnel for a 
GUI front-end to building distributables even on Mac.

And the relevance of all this to the Rev list ? To remind us how much 
there is to be grateful for in having the ease of use and ease of 
distribution provided by RunRev. Rev ain't perfect - but it does have a 
lot of advantages.
